From d9b2b5d1431fad9b84be93d270b4c249a7db63aa Mon Sep 17 00:00:00 2001 From: Jesus Armando Anaya <1445792+JArmandoAnaya@users.noreply.github.com> Date: Wed, 26 Aug 2026 01:51:20 -0700 Subject: [PATCH 1/3] feat(kernel): declare export targets on the exporter port MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit An export target is the model a person will train; each exporter now declares its targets beside the five existing port attributes. The kernel gains the frozen ExportTarget model with its Task, TargetFamily and ResizeStrategy vocabularies and the PreprocessingHints a target carries, pure resolution from a target name to the declaring exporter, and a validate_targets check holding every target's geometries within its exporter's own. ExportTargetNotFound, ExportTargetConflict and InvalidExportTarget are typed in kernel/errors.py and mapped in server/errors.py — no route raises them yet; the exact-correspondence test keeps the table total. Every shipped exporter declares one self-named target, family other, with no trainer tasks, so discovery keeps returning them under the widened port. TuSimple's target names the polyline it writes, because its supported set is empty — everything it carries arrives degraded. --- docs/content/api.md | 4 +- src/visionset/formats/_dummy.py | 3 +

Subject: [PATCH 3/3] feat(formats): the yolo format becomes the ultralytics dialect, beside yolov5-yaml The ultralytics dialect derives its task from the release: segment when it holds a polygon, classify when it holds only classification tags, detect otherwise. Its data.yaml carries path: ., one key per fold present, and names as a mapping with no nc. yolov5-yaml writes the YOLOv5 descriptor grammar for YOLOv7 over the same layout, extracted into _yolo_writer. The registry accepts yolo as an alias of ultralytics and answers the alias beside the plugin, and validates every declaration at the scan. The nine Ultralytics targets and yolov7 are declared. --- .github/workflows/ci.yml | 2 +- CHANGELOG.md | 9 + CONTRIBUTING.md | 2 +- docs/content/api.md | 2 +- docs/content/architecture/backend/formats.md | 5 +- docs/content/cli.md | 4 +- docs/content/releases.md | 109 +++++-- docs/content/releasing.md | 2 +- docs/content/tutorial.md | 34 +- examples/thirty_minute_flow.py | 10 +- pyproject.toml | 3 +- src/visionset/formats/_yolo_writer.py | 250 +++++++++++++++ src/visionset/formats/coco/__init__.py | 4 +- src/visionset/formats/registry.py | 40 ++- src/visionset/formats/ultralytics/__init__.py | 270 ++++++++++++++++ src/visionset/formats/yolo/__init__.py | 270 ---------------- src/visionset/formats/yolov5_yaml/__init__.py | 123 ++++++++ src/visionset/jobs/export.py | 2 +- src/visionset/mcp/releases.py | 2 +- src/visionset/server/models.py | 2 +- src/visionset/server/routes/releases.py | 4 +- src/visionset/wire/__init__.py | 2 +- tests/cli/test_export_commands.py | 30 +- tests/examples/test_mcp_end_to_end.py | 3 +- tests/formats/test_classification.py | 2 +- tests/formats/test_coco.py | 2 +- tests/formats/test_registry.py | 25 +- tests/formats/test_report_agreement.py | 173 +++++++++-- .../{test_yolo.py => test_ultralytics.py} | 130 ++++++-- tests/formats/test_ultralytics_roundtrip.py | 290 ++++++++++++++++++ tests/formats/test_voc.py | 2 +- tests/formats/test_yolo_smoke.py | 220 ------------- tests/formats/test_yolov5_yaml.py | 133 ++++++++ tests/mcp/test_agent_walk.py | 7 +- tests/mcp/test_release_tools.py | 19 +- tests/packaging/test_installed_metadata.py | 2 +- tests/packaging/test_wheel.py | 8 +- 37 files changed, 1551 insertions(+), 646 deletions(-) create mode 100644 src/visionset/formats/_yolo_writer.py create mode 100644 src/visionset/formats/ultralytics/__init__.py delete mode 100644 src/visionset/formats/yolo/__init__.py create mode 100644 src/visionset/formats/yolov5_yaml/__init__.py rename tests/formats/{test_yolo.py => test_ultralytics.py} (81%) create mode 100644 tests/formats/test_ultralytics_roundtrip.py delete mode 100644 tests/formats/test_yolo_smoke.py create mode 100644 tests/formats/test_yolov5_yaml.py diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index d7ef4e7e..ebf11d70 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -682,7 +682,7 @@ jobs: # suppresses the count line — which is the line that would show this job # quietly shrinking to nothing. - name: The reference readers load the exports - run: uv run pytest tests/formats/test_yolo_smoke.py tests/formats/test_coco_smoke.py + run: uv run pytest tests/formats/test_ultralytics_roundtrip.py tests/formats/test_coco_smoke.py # #49's performance benchmark: frame times during pan, zoom and drag over 200 # boxes and 20 polygons of 32 vertices on a 4K asset, plus a CPU-throttling diff --git a/CHANGELOG.md b/CHANGELOG.md index 0673a0e5..e9819a25 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -83,6 +83,15 @@ nothing was being distributed.
